Two figures dominate early direct flights to and from New Zealand:
Charles Kingsford Smith and Charles Ulm.

They made the first trans-Pacific flight from the USA to
Australia in May/June 1928 in
the Southern Cross, a Fokker monoplane and followed
that with the first trans-Tasman flight to New Zealand in September.

Kingsford Smith and Ulm

The first stamps to honour Kingsford Smith were issued by
Australia as early as 1931.
Australia issued stamps in
1978
depicting both Kingsford Smith and Ulm
to commemorate the 50th anniversary of the trans-Pacific
flight.

Early trans-Tasman flights

Flying the Southern Cross, Kingsford Smith and Ulm made the
first trans-Tasman flight from Sydney to Christchurch
on 10 September 1928 and the return flight from Blenheim to
Sydney on 13 October.

This was commemorated by a special stamp issue by both
Australia and New Zealand in
1958 showing Kingsford Smith and the
Southern Cross.

In 1933, Kingsford Smith and Ulm
both made unofficial airmail flights between
Australia and New Zealand as they tried to persuade the
authorities to agree to an official airmail.

In October 1934, after taking part in the
MacRobertson Air Race
from London to Melbourne, Hewitt and Kay
continued their flight to New Zealand.
They carried the first (unofficial) air mail that had been
flown all the way from the UK to New Zealand.

In May 1935, Kingsford Smith planned a flight from
Australia to New Zealand and return to commemorate the
Jubilee of George V.
The return flight would then connect with the regular
Australia - UK airmail.
However, the flight from Australia
had to be abandoned half way across the Tasman Sea.

In March 1938, Clouston and Ricketts
flew from the UK to
New Zealand and return in a record time.
They left London on 15 March, arrived in Blenheim on 21 March
and were back in London by 26 March.
Their plane was the DH 88 Comet that had won
the MacRobertson Air Race
in 1934.

Scheduled services

Although the United Kingdom was keen to set up an
Empire airmail scheme linking the countries of the Empire,
New Zealand was the last link and it was April 1940 before a
regular trans-Tasman
airmail service
was set up by Tasman Empire Airways (TEAL)
connecting with established services via Australia.
Although the trans-Tasman service continued, the through airmail
route to the UK was suspended in June 1940
when Italy entered World War II.
